David revealed that King came to visit him last year after he had a stroke.

"I get an email from Robin Furth, who is my co-writer on Dark Tower, and she says, 'Stephen would like your email. Can I give him your email address?' So I go, 'Sure!'" said David.

"So I get an email from Stephen King, and Stephen says, 'I'd like to come up and visit you, you know, up in the hospital. I'm down in Florida'...

"And he drove up. And I thought that he was in Jacksonville. No - he was five hours away. He did a five-hour drive to come up and see me, because I think he was really relating to the concept that I was having to teach myself how to walk again. Because he had to go through the same thing when he got hit by that van, so this was really his wheelhouse."
